PATENTED 1 01973 3.72631 8 SHEET 3 OF FAUCET This invention relates to faucets. More particularly, this invention is directed to a faucet of the type disclosed in U.S. Pat. No. 3,410,487.

The faucet of U.S. Pat. No. 3,410,487 is adapted to be operated with one hand. That is, the temperature, volume and direction of a stream of water flowing from the faucets spout can be controlled by manipulating a single knob associated with the spout. As a result of this novel structural faucet concept, a stream of water of selected temperature and volume can be directed into any area of a sink or lavatory bowl, whether the bowl be single or double.

The faucet of U.S. Pat. No. 3,410,487 includes a base adapted to be mounted on the deck at the rear of a sink or lavatory bowl. The spout itself is mounted at the outer end of two arms which are connected to the base. Valving associated with the base controls the flow of water from hot andcold water supply lines through the respective arms to the spout. This valving in the base is arranged such that the water flow is off when the arms are raised and is turned progressively on as the arms are lowered, the arms thus swinging in an are about a horizontal axis in the base. The base is further adapted to permit the arms to be swung from side to side about a vertical axis, thereby permitting the spout to be moved from one side of a sink or lavatory bowl to the other, as desired.

Valving associated with the spout is arranged such that rotation of the knob controls the temperature of water issuing from the spout within the limits of the temperature of the water available in the supply lines. Additionally, the spout itself may be rotated in an are about a horizontal axis relative to the arms, thus allowing water to be directed against the desired side wall and bottom areas of a bowl. Valving associated with the spout at the outer ends of the arms is also provided, and this Valving functions to diminish the flow of water from the spout as the spout is rotated about its horizontal axis toward the rim of the sink or lavatory bowl so as to prevent water from being directed outside of the bowl.

The faucet of this invention retains the operational features and advantages, i.e., retains the basic structural concept, of the faucet disclosed in U.S. Pat. No. 3,410,487. This invention is concerned primarily with improved structural features, and the advantages thereof, that implement the basic structural concept taught in U.S. Pat. No. 3,410,487. The faucet disclosed in that patent is of relatively simplified construction, but it is desirable from a manufacturing or production standpoint to make a faucet structure of as few parts as is possible so that initial assembly of the faucet is easy and, thereby, less costly. Further, it is highly desirable that the faucet construction be readily serviceable by a person not particularly skilled in the plumbing art; this isparticularly the case where the faucet is adapted for usein a home.

Therefore, it has been one objective of this invention to provide a faucet structure that .is an improvement over that faucet structure disclosed in U.S. Pat. No. 3,410,487, but which retains the operational features and advantages of that'faucet structure.

It has been another objective of this invention to provide a faucet structure of the type disclosed in U.S. Pat.

No. 3,410,487 that involves only a few major components, and that allows those major components to be easily assembled into and disassembled from an operating unit, thereby providing easy initial assembly and repair of the faucet.

It has been still another objective of this invention to provide a faucet structure of the type disclosed in U.S. Pat. No. 3,410,487 wherein the major components may be readily assembled and disassembled by hand without the use of tools.

The faucet 10 of this invention (see FIG. 1) comprises four major components, namely, a base 11, a head 12, and two water supply arms 13 that interconnect the base and the head. The head 12 includes a control knob 14 and a spout 15.

The base 11 (and, hence, the faucet 10) may be mounted on a deck 16 at the rearof a double sink bowl 17. The faucets head 12 and arms 13 are adapted to swing about a first vertical axis 18 so that the head 12 can be moved'from one bowl to the other of a double sink bowl 17. The arms 13 are pivotable about a first horizontal axis 19 (that intersects the first vertical axis 18) so that the water flow can be turned on and off. The head's control knob 14 is adapted to oscillate about a second vertical axis 20 so that the mixture of hot water flowing through hot water arm 18a, and of cold water flowing through cold water arm 11%, can be controlled to provide the desired water-temperature. The heads spout 15 is adapted to swing about a second horizontal axis 21 to direct the water flow against any portion of the bowls side wall 22 or bottom 23 surface areas as desired. Hotwater feed pipe 24 and cold water feed pipe 25 supply the faucet 10 with hot and cold running water.

The major part of the base 11 is a core 28. As shown in FIGS. 2 and 4, the core 28 comprises a generally cylindrical vertical column 29 and a horizontal barrel 30 located atop the vertical column, these two portions being molded integral one with the other. The vertical column 29 of the core 28 has two bores 31 extending vertically therethrough that are formed by drilling upward from bottom 32, the axes of the bores 31 being in a plane transverse to the swing axis 19 of barrel 30; bore 31a is for hot water and bore 31b is for cold water. Plugs 33 seal off the columns bottom 32 from the bores 31. The vertical column 29 is surrounded by a sleeve 34 (also a part of the base 11), these two parts being dimensioned such that there is an easy slip fit between them. A snap clip 35 received in columns annular groove 36 serves to support the sleeve 34 in axial alignment with, and in operating assembly with,'the vertical column. Upon installation with the sink bowls deck 16, the barrel 30 is located above the deck and the major portion of the column 29 and sleeve 34 are located below the deck. Because the column 29 is in a slip fit relation with sleeve 34, rotation of the column (and, hence, the arms 13 and head 12) about vertical axis 18 is made possible to allow movement of the head from one of the double sink bowls 17 to the other.

Adjacent the bottom 32 of the core 28, and beneath the sink bowls deck 16, annular grooves 37 (to receive O-rings 38) are formed in the columns outer surface. These O-rings 38 seal off two annular chambers 39, 40 (one being located above the other) formed by cooperation of annular grooves 41 in the columns outer surface and the sleeves inner surface. Such grooves 41, by reason of notches 42, allow chambers 39, 40 to communicate with the columns bores 31. Hence, the annular chamber 39 is a hot water chamber and is connected, through a port 43 and threaded connector piece 44 (molded integral with sleeve 34), to a conventional water pipe coupling 45 and, hence, to hot water supply pipe 24. In a similar manner, the annular chamber 40 is a cold water chamber and is connected, through a port 46 and threaded connector piece 47 (molded integral with sleeve 34), to a conventional water pipe coupling 48 and, hence, to cold water supply pipe 25. Because of O-rings 38, no mixture of the hot and cold water takes place as such .water flows into the column from supply lines 24, 25. Further, because of annular chambers 39, 40 and O-rings 38, hot and cold water is always being supplied to bores 31a, 31b no matter what the position of arms 13 and head 12 about vertical axis 18, i.e., no matter which bowl of the double sink bowl 17 the head is directing water into.

The base 11 is adapted to be fixed to the rear deck of the sink bowls l7, and to the supporting wood frame 52, by a mounting assembly generally indicated at 53, see FIG. 4. The base '5 sleeve 34 carries a metal ring 54 adjacent the top rim 55 thereof. An escutcheon ring 56 is positioned beneath the metal ring and a rubber gasket 57 is positioned therebetween, the escutcheon ring being located on top of the rear deck. Thus, the base 11 is vertically positioned relative to the sinks rear deck by the escutcheon ring 56. The base 11 is locked or made immobile relative to the deck 16 of the sink bowl through use of a force ring 58 having an inner diameter sufficient to permit same to rest on annular ledge 59 provided intermediate the length of the sleeve 34 (and beneath the deck 16). To attach the base 11 (and, hence, the faucet 10) to the sink bowls deck 16, bolts 60 are simply threaded into the force ring 58 and tightened against the underside of the deck, thereby immobilizing the base 11 on the deck.

It is noted at this point that the bases column 29, and those faucet parts that are attached to it, can be removed from installation on the deck 16 simply by removing the snap clip 35 at the bottom of the column. That is, from a practical standpoint it is the bases sleeve 34 which is fixed to the deck 16 with the bases column 29 (and, hence, the whole faucet 10 except for the sleeve 34 and mounting assembly 53) being easily removed therefrom simply by removing snap clip 35 and drawing the column 29 upwardly. It is not necessary to remove the hot 24 and cold 25 water supply lines from the faucet 10 to remove the faucet from the deck as is required with conventional faucets.

The hot 31a and cold 31b water bores that extend vertically through column 29 stop short of the axis 19 of the barrel 30; thus, bore 31a intersects stepped bore 64a and bore 31b intersects stepped bore 64b in the barrel. These stepped bores 64a, 64b extend horizontally in opposite directions from one another with bore 64a (which essentially is an extension of bore 31a) terminating at barrel face 65 and bore 64b (which essentially is an extension of bore 31b) terminating at barrel face 66. The two bores 64 are formed by drilling in from opposite side faces 65, 66 of the barrel 30. Note that the axes of these two bores 64a, 64b do not correspond one with the other, i.e., they are not coaxial, even though both are parallel to the barrels axis 19. This pennits the barrel 30 to be relatively short as its length need only be sufficient to accommodate one stepped bore 64 since they are located parallel one to the other instead of coaxial one to the other.

The arms 13 provide bores 76a, 76b through which both hot (76a) and cold (76b) water is conducted from the base 11 into the head 12, see FIGS. 2 and 3. Each arm 13a, 13b is molded integral with a barrel hub portion 77, 78 having an axis transverse to the arms 13a, 13b respectively. The arms barrel hubs 77, 78 are circular plugs in configuration and are adapted to be received in barrel seats 80, see FIG. 2. The barrel seats are defined by rims 81 which extend outward from opposite side faces 65,66 of the barrel, the rims being circular in configuration and being coaxial with the axis 19 of the barrel 30. Thus, in assembly with the barrel 30, the arms barrel hubs 77 78 are coaxial with the barrels axis 19. Each hub 77, 78, on its outer periphery, is provided with two annular grooves each of which carries an O-ring 79. The hubs 77, 78 are of an outside diameter approximately equal to the inside diameter of the barrels rims 81, and the inner surface of the rim cooperates with the O-rings on the hubs to create a sealing relation as the hubs are slip fit into the seats 80. Further this slip fit relation between the arms barrel hubs 77, 78 and the barrels seats 80 is such as to permit swinging motion of the arms 13a, 13b relative to the barrel 30 about the axis 19; this is most important in the operation of the faucet 10 in that such swinging motion permits the volume of hot and cold water from the input lines 24, 25 to the faucet's head 12 to be turned on and off as is explained immediately below.

- Note that the arms barrel hubs 77, 78 define arcuate ports 84a and 84b respectively that communicate with bores 76a, 76b in the arms 13a, 13b, see FIGS. 2, 8 and 9. These arcuate ports 84a, 84b are adapted to cooperate with bores 64a, 64b in the bases barrel 30 to permit water to pass through the barrel and the hubs 77, 78 into the arms bores 76a, 76b. As the arms 13a, 13b and, hence, the barrel hubs 77, 78 are rotated in a plane transverse to the axis 19 of the barrel 30 (i.e., are swung about the axis 19), the arcuate ports 84a, 84b in the hubs shift relative to stepped bores 64a, 64b in the bases barrel 30 (compare particularly FIGS. 8 and 8A relative to hot water arm 13a, and FIGS. 9 and 9A relative to cold water arm 13b). Swinging of the water arms 13 brings arcuate ports 84 a, 84bin the arms barrel hubs 77, 78 into and out of alignment with stepped bores 64a, 64b in the bases barrel 30, thereby permitting the faucet to be turned full on when the arms 13 are lowered (see FIGS. 8 and 9) or completely off when the arms 13 are raised (see FIGS. 8A and 9A). It will be" understood that the arcuate port 84a of the hot water hub 77 is shorter than the arcuate port 84b of the cold water hub 78 because the barrels hot water bore 64a is placed in front of the barrels cold water bore 641;, see FIG. 4. Each stepped bore 64 receives a spring 67 and a tubular seal 68, each seal 68 being spring biased against flat hub faces 69, 70 of the water supply arms 13 when same are assembled with the base 11, see FIG. 3. That is, seals 68 are provided between hot 31a, 64a and cold 31b, 64b water bores in column 29, and hot 76a and cold 7611 water bores in arms 13 to prevent mixing of the hot and cold water as it flows from the bases barrel 30 portion into the arms 13.

The two arms 13 are held in operative engagement with the bases barrel 30 by a first yoke 85, see FIGS. 2 and 4. The first yoke 85 is provided with a hole 86 in its floor 87 which permits the yoke to be slid over the bases column 29 into seating relation with the underside of the barrel 30. When in assembled relation, the yokes floor 87 abuts against flange 88 molded into the column. The yoke 85 is held in assembled relation with the base 11 because of bases sleeve 34 forcing the yokes floor 87 from the underside against the columns flange 88, see FIG. 4. The yoke 85 further includes ears 90 spaced one from the other a distance substantially equivalent to the axial length of the bases barrel 30 portion (not including rims 81) plus the axial length of both hubs 77, 78. The first yoke 85 is also provided with front and rear side walls 93 and 94 which aid in structurally reinforcing same. When the arms hubs 77 78 are positioned in barrels seats 80, yoke 85 grips the arms hubs between its cars 90 to hold the arms 13a, 13b in operating assembly with the base 11. Such permits swinging motion of the arms 13 relative to the barrel base 11 because of the planar bearing surfaces defined by thehubs outside surfaces 91 and the ears inside surfaces 92, see FIGS. 1 and 3. Note that front edge 93 and rear edge 94 of the yoke 85 are molded into the yoke so as to act as stops for the swinging motion of the arms 13. That is, the yokes front edge or stop 93 limits the lower attitude of the arms 13 by reason of the arms abutting against that edge when in the lower attitude (see FIG. 4), and the yokes rear edge or stop 94 limits the upper attitude of the arms 13 by reason of the arms abutting against that edge when axes are parallel. Each head hub 96,97 defines a bore 98a, 98b that terminates at planar face 101, 102 of the hubs and intersects the arms bores 76a, 76b respectively. In assembly with the head 12 these two head hubs 96, 97 are coaxial with heads horizontalaxis 21.

The heads spout 15 includes a vertical bore 103 and a horizontal bore 104, the two bores intersecting at the middle of the molded, one-piece spout 15, see FIGS. 2, 3 and 7. The horizontal bore 104 is partially defined by two pipes 105, one of which extends from each side face 107, 108 of the spout 15. Each pipe 105 is surrounded by a rim 109 integral with the spout 15, the rims and pipes being coaxial with heads axis 21, and cooperating to define seats 110 adapted to receive the arms head hubs 96, 97. The head hub 96, 97 on each arm 13a, 13b is of an outside diameter substantially equal to the inside diameter of heads rims 109, and each hub is provided with two grooves that receive 0- rings 111. As the arms head hubs 96, 97 are slipped over the heads pipes 105, they are received in a slip fit relation with the heads seats 110. This slip fit relation is such as to permit swinging motion of the head 12 relative to the arms 13 about the axis 21; this is most important in operation of the faucet as it allows water tobe directed against the sink bowls side walls.

The pipes 105 are each provided with a cutout or notch 112 at their outer ends, and these notches are adapted to cooperate with the bores 76a, 76b in the arms 13. As the spout 15 is rotated relative to the arms 13 about the axis 21, the hot 76a and cold 76b water bores 76a, 76b to close off the head 12 from the arms water bores.

The head's two pipes molded integral with the spout 15 open into the vertical discharge bore 103 that extends through the spout, see FIG. 7. This discharge bore 103 is of two differentdiameters and provides sloping shoulder 115 that interconnects the different diameter bore sections. The discharge bore 103 receives barrel valve 116 in a slip fit relationship, see

FIGS. 2 and 7. The barrel valves tapered lower portion 118 is of a larger diameterwthan the upper portion 119, and allows the valve to be vertically positioned within the discharge bore 103 and seated against sloping shoulder 115. The valves upper portion 119 has two grooves which receive O-rings 120,- thereby providing a sealing relation in the discharge bore 103 above the pipes 105 to prevent water from spitting out the top of the head 12. The valves upper portion 119 includes a stem 121 having a flat 122 thereon. The stems flat 122 cooperates with the knobs flat 123 to prevent the knob 14 from turning relative to the valves stem 121; a set screw 124 locks the barrel valve in place relative to its axial position in the discharge bore 103, and locks the knob to the valves stem. The valves lower portion 118 has a vertical bore 125 therein, and this bore 125 opens to a cross slot 126 out so as to interconnect with bore 125. The cross slot 126 is so positioned that, when the barrel valve 116 is positioned within the spouts discharge bore 103, the slot 126 can be turned to interconnect with either or both the pipes 105a, 105b. When the cross slot 126 is arranged such that its sides are open equally to the hot 105a and cold 105b water inlet pipes (as is the case in FIG. 3), equal mixtures of hot and cold water will be discharged from the spout when the cross slot 126 is rotated toward the cold water line 105b, more cold water than hot (i.e., a cool water flow) is discharged from the spout; and when the cross slot 126 is rotated toward the hot water line 105a, more hot water than cold (i.e., a warm water flow) is discharged from the spout. It can be seen, therefore, that by rotating the control knob 14 about an axis (which is spaced from but in a plane common to the vertical axis 18) that a water temperature control is provided. The discharge bore 103 preferably has a conventional aerator 117 threaded thereinto at the bores terminus.

The spout 15 also includes a collar 127 on the top thereof that is coaxial with the discharge bores upper portion 119, the collar 127 including stop 128 that cooperates with stop 129 fixed to the underside of the knob 14. As illustrated in FIG. '7, the knob 14 is mounted on the spout 15 such that as the knob is rotated relative to the spout so as to change the barrel valves position, the knob's stop 129 slides on the top of spouts collar 127 and the spouts stop 128 slides on the collar surface of the knob. Thus, the stops 128, 129 (each of which are of an arcuate length approximately equal to A; the peripheral length of the spouts collar 127) cooperate to limit the movement of the knob 14 (and, hence, the barrel valve 116) to an oscillatory movement (as opposed to a rotary movement) between a position at which the stem 121 is turned full left (cold water only since hot water pipe 105a is blocked, refer to FIG. 3) and a position at which the stem 121 is turned full right (hot water only since cold water pipe 10Sb is blocked, refer to FIG. 3). That is, the extreme right hand turn and left hand turn limits on the barrel valve's cross slot 126 (i.e., on the knob 14 since same is used to oscillate the barrel valve 116) is determined by cooperation of knobs stop 129 with spouts stop 128.

The arms 13 are held in operative relation with the head 12, i.e., the arms head hubs 96, 97 are kept seated in head's seats 110, bya second yoke 113, see FIGS. 2, 3 and 7. The yoke 113 defines a hole 114 received over the top collar of the head. When in assembled relation, the yokes floor 135 is seated on top of ledge 136 formed on spout 15, see FIGS. 2 and 7. The yoke 113 is held in assembled relation with the head 12 by reason of knobs surface 137 overlying yokes floor 135, see FIG. 7. The yoke 113 is also provided with ears 138 that grip the head hubs 96, 97 and head 12 therebetween to compress same into an operative assembly when the arms head hubs 96, 97 are positioned and in heads seats 110, see FIGS. 2 and 3. The ears 138 are molded integral with the yoke collar 139, shoulder 140, and side 141. Such permits swinging motion of the head 12 relative to the arms 13 because of the planar bearing surfaces defined by the hubs outside surfaces 142 and the ears inside surfaces 143, see FIG. 3. Note in FIG. 83 that rear edge 145 of the yoke 113 is molded into the yoke so as to act as a stop for the swinging motion of the head 12. That is, the yoke s stop 148 limits the counterclockwise motion of the head 12 (as viewed in FIG. 8) by reason of the arms 13 abutting against the edge 145 when the head is rotated counterclockwise. This, of course, limits the arcuate swinging motion of the head about the horizontal axis 21.

It may be seen, therefore, that three controls of the faucet 10 can be accomplished by grasping the knob 14. The first of these is the on/off and volume control; such is accomplished by raising or lowering the head 12 (i.e., swinging the arms 13 about the horizontal axis 19) because of arms barrel hubs 77, 78 rotating in bases seats 80. The second of these is moving the position of the head 12 relative to the sinks bowls 17 as desired and needed; such is accomplished by swinging the arms 13 from side to side (i.e., about the vertical axis 18) because of bases column 29 rotating in sleeve 34, and by swinging the head 12 front to rear (i.e., about the horizontal axis 21) because of arms head hubs 96, 97 rotating in heads seats 110. The third of these is the control of the waters temperature flowing from the spout 15; such is accomplished by rotating the knob 14 about spouts axis 20 between limits as determined by stops 128, 129.

While the faucet disclosed in US. Pat. No. 3,410,487 has established a true advance in the art, the faucet of this invention is an improvement thereon in the sense of simplicity of initial construction, of initial assembly into an operating attitude, and of disassembly and reassembly for repair. Such is in part due to the fact that arms 1.3 are provided with head hubs 96, 97 and barrel hubs 77, 78 which cooperate with and are seated in seats 110, defined in head 12 and base 11 respectively; this allows the arms 13 to be readily assembled, disassembled and reassembled with the head 12 and base 11 by means of an easy slip fit relationship that is made watertight by the hubs O-rings 79, 111. Further, and importantly, the arms 13 are held and maintained in seated relation with the bases barrel 30 and the head 12 by yokes 85, 113. Further, because the bases column 29 (and, hence, the arms 13 and head 12) are fixed to the sinks deck 16 only by reason of the column 29 being locked in sleeve 34 by snap ring 35, the entire faucet (except for the sleeve 34 and mounting assembly 53) can be easily removed from the sinks deck simply by removing the snap ring 35 from columns annular groove 36 and sliding the column 29 upwardly out of the sleeve. A further advantage is that the bore 64a, 64b configuration in the base s barrel 30 allows the barrel length to be relatively short because the bores 64a, 64b are located parallel one to the other, and to the axis of the barrel, instead of coaxial with one another as in US. Pat. No. 3,410,487; such a feature is made possible in part because the columns bores 31a, 31b are in a plane that is substantially transverse to the barrels axis 19.

Having described the preferred embodiment of my invention, what I desire to claim and protect by Letters Patent is:

1. A hot/cold water faucet comprising a base adapted for mounting onto the rear deck of a sink bowl, said base defining a hot water bore and a cold water bore adapted to be respectively interconnected with a hot water supply line and a cold water supply line,

a pair of arms connected at one end to said base and adapted for swinging movement about a first horizontal axis through said base, one of said arms defining a hot water bore and the other of said arms defining a cold water bore,
